Dr Ermann is an amazing personality and a person who listens patiently and in detail to their patients. I am very happy to choose him as my provider and would recommend to others to go see him without any second thoughts.

This was the first time I had been seen by Dr. Ermann. He obviously spent some moments looking over my chart because he seemed to be well acquainted with my history, which felt very comforting. I thought he was skillful and I am comfortable seeing him in the future.

I can't say enough good things about my provider. He was extremely understanding and kind. He is the only provider I have seen where I felt he was listening without judgement and his goal was to provide the best care possible for my illness. If I lived closer, I would be grateful to have him as my rheumatologist.

Dr. Ermann is a tremendous doctor. He takes care and pride in his work. Unfortunately, there wasn't anyone available to take my vitals, but that's okay because he handled it. He did it all himself. He's a tremendous doctor.

Dr. Ermann is excellent. He is professional, friendly, makes you feel at ease and listens to you. I never feel rushed and I like that he provides options and his opinions on treatment options but allows me to direct my care. I highly respect his bedside manner and knowledge and always feel comfortable discussing my disease symptoms with him. I would absolutely highly recommend him to anyone in need of an excellent rheumatologist.

Real smart guy, but he had very very short patience, I thought he might've been mad with me. Very hard to read although in the end, he seemed to have a plan so we'll see how it goes.

Unfortunately Dr Erhmann didn't read my record before the visit. This lead to talking in circles. He contradicted what other doctors told me and left me feeling unheard and confused.

Dr. Ermann listened to my concerns, ordered tests that I asked for to see a broader image of my problems, and explained everything to me very thoroughly. When he determined my issue to be outside of his scope of care, he referred me to a colleague who he believes can help me, which I really appreciated

This doctor was wonderful and listened to me carefully and explained everything beautifully. He treated me with respect and kindness. It was such a pleasure feeling so well taken care of. He personally responded to me right away when I asked him a question through the Portal and took a great deal of time explaining everything to me. I highly recommend this doctor!
